Description

本発明は、電力配電システム、電力送電装置、電力受電装置、電力送電方法および電力受電方法に関する。   The present invention relates to a power distribution system, a power transmission device, a power reception device, a power transmission method, and a power reception method.

従来の交流による電力送配電網の構成はおおよそ以下の通りとなっている。   The configuration of a conventional power transmission / distribution network using alternating current is roughly as follows.

発電所は、水力・火力・電子力とそのエネルギー源は様々であるが、家庭や企業等の実際の消費地からは離れている場合が多く、発電所から直接電力を供給しようとすると電圧が低下してしまう。従って、発電所と消費地との間には、電圧の変換を行う変電所が介在するのが一般的である。その変電所は、発電所と消費地との間に複数個存在するのが一般的であり、また発電所から消費地までの系統は一つに限られず、一つの発電所は複数の変電所に電力を供給するし、一つの変電所も複数の発電所から電力供給を受ける。これが電力網といわれる所以である。   Power plants have a variety of energy sources such as hydropower, thermal power, and electronic power, but they are often far away from the actual consumption areas such as homes and businesses. It will decline. Therefore, a substation for converting voltage is generally interposed between the power plant and the consumption area. In general, there are multiple substations between the power plant and the consumption area, and the number of systems from the power plant to the consumption area is not limited to one. The substation also receives power from multiple power plants. This is why it is called a power grid.

発電所と変電所との間は送電線で結ばれ、その送電線の距離は、その間の直流抵抗や地面との間のキャパシタンスが到底無視できない長さとなっている。従って、従来においては、出来るだけ電圧を高くして送電する等、電流を減らす工夫がなされてきた。一方、変電所は、複数の発電所からの電力を入力可能な構造となっているのが基本である（一つの発電所からしか電力が供給されない構成もある）。これは、変電所に接続されているユーザの要求電力が増加した場合に複数の発電所からの電力でまかなうことが目的である。従って、変電所では常に負荷状態を監視し、最終的には発電所の発電量を調整することになる。電力送配電網における配電損失を最小にするための技術としては、例えば特許文献１がある。   The power plant and the substation are connected by a transmission line, and the distance of the transmission line is such a length that the direct current resistance and the capacitance with the ground cannot be ignored. Therefore, in the past, contrivances have been made to reduce the current, for example, by transmitting the power as high as possible. On the other hand, a substation basically has a structure in which power from a plurality of power plants can be input (there is a configuration in which power is supplied only from one power plant). The purpose of this is to cover with power from a plurality of power plants when the power demand of the user connected to the substation increases. Therefore, the substation always monitors the load state, and finally adjusts the power generation amount of the power plant. As a technique for minimizing the power distribution loss in the power transmission / distribution network, for example, Patent Document 1 is known.

現在敷設されている電力送配電網においては、発電所、変電所、および発電所と変電所とを結びつける送配電網の構成が変更されることは少ない。すなわち、変電所に接続される発電所が、日々ダイナミックに変化することは無い。   In the power transmission / distribution network currently laid, the configuration of the power transmission / distribution network connecting the power plant, the substation, and the power plant / substation is rarely changed. That is, the power plant connected to the substation does not change dynamically every day.

しかし、太陽光、風力、バイオマス等のいわゆる自然エネルギーを用いた発電装置は、その設置や廃止が、現状の交流による電力送配電網に比べれば遥かに頻繁に発生する。この状況は、今後これらの発電装置が普及するに連れて進展が考えられる。従って、発電装置、変電装置、および発電装置と変電装置とを結びつける送配電網の構成がダイナミックに変更されることが多くなり、従来の技術では、このようなダイナミックな変更に対処できない問題があった。   However, power generators using so-called natural energy such as sunlight, wind power, and biomass are installed and abolished much more frequently than current power transmission and distribution networks using alternating current. This situation is likely to progress as these power generation devices become more widespread. Therefore, the configuration of the power generation device, the substation device, and the transmission / distribution network that connects the power generation device and the substation device is often dynamically changed, and there is a problem that the conventional technology cannot cope with such a dynamic change.

〔１〕従来の電力配電システムの構成の一例
まず、本発明の好適な実施の形態を説明する前に、従来の電力配電システムの構成の一例について説明する。図４は、従来の電力配電システムの構成の一例について説明する説明図である。以下、図４を用いて従来の電力配電システムの構成の一例について説明する。 [1] Example of Configuration of Conventional Power Distribution System First, an example of the configuration of a conventional power distribution system will be described before describing a preferred embodiment of the present invention. FIG. 4 is an explanatory diagram illustrating an example of a configuration of a conventional power distribution system. Hereinafter, an example of the configuration of a conventional power distribution system will be described with reference to FIG.

図４に示したように、従来の電力配電システムは、例えば、発電を行う発電装置１ａ、１ｂ、５と、発電装置で発電された電力の電圧を変換する変電装置３、４と、供給された電力を消費する負荷６、７、８と、電力を伝送する送電線２ａ、２ｂ、３ａ、３ｂ、４ａ，４ｂ、５ａと、を含んで構成される。   As shown in FIG. 4, a conventional power distribution system is supplied with, for example, power generation devices 1a, 1b, and 5 that generate power, and transformers 3 and 4 that convert the voltage of the power generated by the power generation device. Load 6, 7, 8 that consumes the power and power transmission lines 2 a, 2 b, 3 a, 3 b, 4 a, 4 b, 5 a that transmit the power.

発電装置１ａは、送電線２ａで変電装置３と接続されている。そして、発電装置１ｂは、送電線２ｂで同じく変電装置３と接続されている。変電装置３は、さらに別の変電装置４と送電線３ａで接続されているが、変電装置４には、変電装置３とは別の発電装置５と送電線５ａで接続されている。そして、変電装置４は、負荷７と送電線７で、負荷８と送電線で、それぞれ接続されている。   The power generator 1a is connected to the transformer 3 by a power transmission line 2a. And the electric power generating apparatus 1b is similarly connected with the power transformation apparatus 3 with the power transmission line 2b. The substation 3 is further connected to another substation 4 by a power transmission line 3a, but is connected to the substation 4 by a power generation unit 5 different from the substation 3 and a power transmission line 5a. And the transformation device 4 is connected by the load 7 and the power transmission line 7, and the load 8 and the power transmission line, respectively.

図４に示したような従来の電力配電システムでは、各送電線に配電される電力量は、発電装置や変電装置の能力、負荷での電力消費量に応じて、自動的に、または人間の手によって手動で制御がなされる。従って、従来の電力配電システムでは、このように制御がなされることで、システムが破綻しない（例えば、ある送電線が過剰な電力を供給しない）ことが前提となっている。   In the conventional power distribution system as shown in FIG. 4, the amount of power distributed to each transmission line is either automatically or according to the power consumption of the power generation device or the transformation device and the power consumption at the load. Control is done manually by hand. Therefore, in the conventional power distribution system, it is assumed that the system is not broken by such control (for example, a certain transmission line does not supply excessive power).

以上、従来の電力配電システムの構成の一例について説明した。   The example of the configuration of the conventional power distribution system has been described above.

図４に示したような従来の電力配電システムでは、送電線の抵抗や、地面との間のキャパシタンスによって電力の損失が発生する。この電力の損失が、電力配電システム全体としての電力損失という観点からは、最適なものであるかどうかは判断しにくい。また、電力配電システム全体としての電力損失が最適であるかどうかを判断するにしても、電力配電システムの各部の電圧や電流に関する情報をモニタして、モニタした情報を何らかの手段で収集し、分析した上で、最適であるかどうかを判断する必要がある。   In the conventional power distribution system as shown in FIG. 4, power loss occurs due to the resistance of the transmission line and the capacitance with the ground. It is difficult to determine whether this power loss is optimal from the viewpoint of power loss as a whole power distribution system. Even if it is determined whether the power loss of the power distribution system as a whole is optimal, the information on the voltage and current of each part of the power distribution system is monitored, and the monitored information is collected and analyzed by some means. In addition, it is necessary to determine whether it is optimal.

そこで本発明の一実施形態においては、発電装置や変電装置を識別するための固有情報や、発電装置や送電装置から配電される電力に関する情報を発電装置や変電装置から送信する。そして、電力を受け取る変電装置や負荷側で、これらの情報を受信することで、電力配電システム全体としての電力損失を最適化することを目的とする。   Therefore, in one embodiment of the present invention, unique information for identifying the power generation device and the power transformation device and information related to the power distributed from the power generation device and the power transmission device are transmitted from the power generation device and the power transformation device. And it aims at optimizing the power loss as the whole power distribution system by receiving these information in the substation which receives electric power, or the load side.

From the power generation apparatus 101, the electric power I <b> 1 generated internally through the power transmission line 131 is supplied to the transformation apparatus 111. Simultaneously with the supply of the electric power I1, the power generation apparatus 101 transmits information regarding the power generation apparatus 101 and information G1 regarding the power generated by the power generation apparatus 101 to the substation 111 via the power transmission line 131. When transmitting the information G1 from the power generation device 101 to the power transformation device 111, the information G1 may be superimposed on the power distributed by the power transmission line 131. The power transmission line 131 may be provided and transmitted via the communication line. The transmission of the information G1 from the power generation device 101 is not limited to wired communication, and may be performed by wireless communication.

発電装置１０１から送信する情報の内容については後に詳述するが、例えば発電装置を識別するための識別情報、絶対的な位置情報、特定の変電ノードとの間の送電線のインピーダンス情報等を含んでいてもよい。   The details of the information transmitted from the power generation device 101 will be described in detail later, including, for example, identification information for identifying the power generation device, absolute position information, impedance information of a transmission line with a specific substation, and the like. You may go out.

発電装置１０２は、変電装置１１１と送電線１３２で接続されている。発電装置１０１と同様に、発電装置１０２からは、送電線１３２を通じて内部で発電された電力Ｉ２を変電装置１１１に供給する。そして、電力の供給と同時に、発電装置１０２からは送電線１３２を通じて、発電装置１０２に関する情報や、発電装置１０２が発電した電力に関する情報Ｇ２を変電装置１１１に送信する。   The power generation device 102 is connected to the power transformation device 111 by a power transmission line 132. Similarly to the power generation apparatus 101, the power generation apparatus 102 supplies the power I <b> 2 generated internally through the power transmission line 132 to the substation apparatus 111. Simultaneously with the supply of power, the power generation device 102 transmits information related to the power generation device 102 and information G2 related to the power generated by the power generation device 102 to the power transformation device 111 through the power transmission line 132.

変電装置１１１は、発電装置１０１、１０２から電力Ｉ１、Ｉ２の供給を受け、電圧を変換して出力するものである。そして、変電装置１１１は発電装置１０１、１０２から電力の供給を受けると共に、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２を受信するものである。変電装置１１１は、負荷１２１と送電線１３３で接続されており、また変電装置１１２と送電線１３４で接続されている。変電装置１１１は、変圧後の電力Ｉ１、Ｉ２を出力して、送電線１３３、１３４を介して供給すると共に、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２も送信する。   The substation device 111 is supplied with electric power I1 and I2 from the power generation devices 101 and 102, converts the voltage, and outputs the converted voltage. And the power transformation apparatus 111 receives the supply of electric power from the power generation apparatuses 101 and 102, and receives the information G1 and G2 transmitted from the power generation apparatuses 101 and 102. The substation device 111 is connected to the load 121 via a power transmission line 133, and is connected to the substation device 112 via a power transmission line 134. The transformer 111 outputs the transformed power I1 and I2 and supplies them via the power transmission lines 133 and 134, and also transmits information G1 and G2 transmitted from the power generators 101 and 102.

負荷１２１は、変電装置１１１から送電線１３３を介して電力Ｉ１、Ｉ２の供給を受けるものである。そして、負荷１２１は、変電装置１１１から電力の供給を受けると共に、変電装置１１１から送信される、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２も受信するものである。負荷１２１では、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２に基づいて、どの発電装置から供給された電力を消費すれば効率的であるかを判断することが可能となる。負荷１２１、１２２としては、例えば、主に家庭内で使用される電気機器が該当する。そのような電気機器の具体例としては、例えばパーソナルコンピュータ、テレビ、ビデオレコーダ、コンポーネントステレオセット、冷蔵庫、電子レンジその他の機器がある。   The load 121 is supplied with electric power I1 and I2 from the transformer 111 through the power transmission line 133. The load 121 receives power supplied from the power transformation device 111 and also receives information G1 and G2 transmitted from the power generation devices 101 and 102 transmitted from the power transformation device 111. In the load 121, based on the information G1 and G2 transmitted from the power generation devices 101 and 102, it is possible to determine which power supply from which power generation device is consumed is efficient. As the loads 121 and 122, for example, electrical equipment mainly used in the home is applicable. Specific examples of such electric devices include personal computers, televisions, video recorders, component stereo sets, refrigerators, microwave ovens, and other devices.

発電装置１０３は、変電装置１１２と送電線１３５で接続されている。発電装置１０１、１０２と同様に、発電装置１０３からは、送電線１３５を通じて内部で発電された電力Ｉ３を変電装置１１２に供給する。そして、電力の供給と同時に、発電装置１０３からは送電線１３５を通じて、発電装置１０３に関する情報や、発電装置１０３が発電した電力に関する情報Ｇ３を変電装置１１２に送信する。   The power generation device 103 is connected to the power transformation device 112 by a power transmission line 135. Similar to the power generation devices 101 and 102, the power generation device 103 supplies the power I <b> 3 generated internally through the power transmission line 135 to the substation 112. Simultaneously with the supply of power, the power generation device 103 transmits information regarding the power generation device 103 and information G3 regarding the power generated by the power generation device 103 to the power transformation device 112 through the power transmission line 135.

変電装置１１２は、変電装置１１１、および発電装置１０３から電力Ｉ１、Ｉ２、Ｉ３の供給を受け、電圧を変換して出力するものである。そして、変電装置１１２は変電装置１１１、および発電装置１０３から電力Ｉ１、Ｉ２、Ｉ３の供給を受けると共に、変電装置１１１から送信された情報Ｇ１、Ｇ２および発電装置１０３から送信された情報Ｇ３を受信するものである。変電装置１１２は、負荷１２２と送電線１３６で接続されている。変電装置１１２は、変圧後のＩ１、Ｉ２、Ｉ３電力を出力して、送電線１３６を介して供給すると共に、変電装置１１１から送信された情報Ｇ１、Ｇ２および発電装置１０３から送信された情報Ｇ３も送信する。   The substation 112 receives power I1, I2, and I3 from the substation 111 and the power generation apparatus 103, converts the voltage, and outputs the converted voltage. The transformer 112 receives the power I1, I2, and I3 from the transformer 111 and the power generator 103, and receives the information G1 and G2 transmitted from the transformer 111 and the information G3 transmitted from the generator 103. To do. The substation device 112 is connected to the load 122 by a power transmission line 136. The transformer 112 outputs the transformed I1, I2, and I3 powers, supplies them via the transmission line 136, and transmits the information G1 and G2 transmitted from the transformer 111 and the information G3 transmitted from the generator 103. Also send.

負荷１２２は、変電装置１１２から送電線１３６を介して電力Ｉ１、Ｉ２、Ｉ３の供給を受けるものである。そして、負荷１２２は、変電装置１１２から電力の供給を受けると共に、変電装置１１２から送信される、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２、および発電装置１０３から送信された情報Ｇ３も受信するものである。負荷１２２では、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２、および発電装置１０３から送信された情報Ｇ３に基づいて、どの発電装置から供給された電力を消費すれば効率的であるかを判断することが可能となる。   The load 122 receives supply of electric power I1, I2, and I3 via the power transmission line 136 from the transformer device 112. The load 122 receives the supply of power from the power transformation device 112 and also transmits information G1 and G2 transmitted from the power generation devices 101 and 102 and information G3 transmitted from the power generation device 103. To receive. Based on the information G1 and G2 transmitted from the power generation devices 101 and 102 and the information G3 transmitted from the power generation device 103, the load 122 determines which power supply from which power generation device is consumed is efficient. It becomes possible to judge.

図１のように構成されたシステムでは、例えば負荷１２２においては、情報Ｇ１、Ｇ２、Ｇ３を受信することで、現在消費している電力の発電端までの論理距離（物理的な距離に、送配電線のインピーダンスやロスを加味したもの）を知ることができる。そのため、その論理距離が長い場合には（例えば発電装置１０１、１０２と負荷１２２との間の距離が長い場合には）、その発電端で発電された電力の負荷１２２での消費を下げることができる。そして、発電端までの論理距離が短い電力を優先して消費するように制御することで、配電システム全体としての送電線による電力ロスを小さくするような電力消費が可能となる。   In the system configured as shown in FIG. 1, for example, the load 122 receives information G1, G2, and G3, so that the logical distance (physical distance to the power generation end) of the currently consumed power is transmitted. It is possible to know the distribution line impedance and loss). Therefore, when the logical distance is long (for example, when the distance between the power generation devices 101 and 102 and the load 122 is long), the consumption of the power generated at the power generation end at the load 122 can be reduced. it can. And by controlling so that electric power with a short logical distance to the power generation end is consumed preferentially, it becomes possible to consume electric power so as to reduce the power loss due to the transmission line as the entire power distribution system.

また、変電装置１１１、１１２においても、上流にある電力減までの論理距離を知ることが出来る。従って、上流の電力源が単一で無い限り、下流への供給電力をどの電力源から得るかを選択することが出来る。従来の電力配電システムでは、上流の電力源（発電所）はほぼ固定されており、予め論理距離が一番近い発電所からの電力を優先して得ることとするように指定すれば同様の機能を実現することが出来る。しかし、従来の電力配電システムでは、上流の電力源が頻繁に入れ替わることは無い。よって、仮に論理距離が一番近い発電所が廃止されたり、新たに論理距離が一番近い発電所が設けられたりすると、別の発電所を論理距離が一番近い発電所として人間の手で再度設定し直さなければいけない。これに対して本発明の一実施形態にかかる電力配電システム１００では、変電装置１１１、１１２は発電装置１０１、１０２、１０３から送信される情報を随時受信することができる。従って、発電装置の新たな設置や、発電装置の撤去に応じて、受信する情報から、どの発電装置からの電力を消費すれば最も効率的かを判断することが出来る。   In addition, the transformers 111 and 112 can also know the logical distance to the power reduction upstream. Therefore, as long as there is no single upstream power source, it is possible to select from which power source the downstream power supply is obtained. In the conventional power distribution system, the upstream power source (power plant) is almost fixed, and the same function can be used if it is specified in advance that power from the power plant with the nearest logical distance is given priority. Can be realized. However, in the conventional power distribution system, the upstream power source does not frequently change. Therefore, if the power station with the closest logical distance is abolished or a new power station with the closest logical distance is established, another power station will be set as the power station with the closest logical distance by human hands. You must set it again. On the other hand, in the power distribution system 100 according to the embodiment of the present invention, the substation devices 111 and 112 can receive information transmitted from the power generation devices 101, 102, and 103 at any time. Therefore, according to the new installation of the power generation device or the removal of the power generation device, it is possible to determine from the received information which power generation device consumes the most efficient power.

例えば、変電装置１１２が電力の供給を受けている発電装置１０１、１０２、１０３の内、論理距離が一番短い発電装置が発電装置１０３だった場合を考える。この場合に、発電装置１０３が電力配電システム１００から撤去されると、変電装置１１２は発電装置１０１、１０２が送信した情報を随時受信している。従って、変電装置１１２は発電装置１０１、１０２のどちらが最も論理距離が短い発電装置であるかどうかを自動的に判断することができる。   For example, consider a case where the power generation device having the shortest logical distance is the power generation device 103 among the power generation devices 101, 102, and 103 to which the power transformation device 112 is supplied with power. In this case, when the power generation device 103 is removed from the power distribution system 100, the power transformation device 112 receives information transmitted from the power generation devices 101 and 102 as needed. Therefore, the substation device 112 can automatically determine which of the power generation devices 101 and 102 is the power generation device with the shortest logical distance.

（２）発電する電力の物理仕様に関する情報としては、例えば現状の出力電圧、公称出力電圧、現状の出力電流、公称出力電流、最大出力電流、最大出力、現状の出力、緯度・経度等の位置情報を含んでいても良い。これら以外にも、発電する電力の物理仕様に関する情報としては、例えば特定の変電ノードとの間の送電線のインピーダンス等を含んでいてもよい。   (2) Information on the physical specifications of power to be generated includes, for example, current output voltage, nominal output voltage, current output current, nominal output current, maximum output current, maximum output, current output, position such as latitude and longitude Information may be included. In addition to these, the information related to the physical specifications of the power to be generated may include, for example, the impedance of a transmission line with a specific substation node.

（３）発電する電力のコストや経費に関する情報としては、例えば各発電所が発電している電力の単価を配分し直し、変電装置で必要になる費用やコストを加算した電力単価、発電している電力の単位電力あたりの二酸化炭素発生量、電力の変電回数（変電装置を通過する度に１増加する）、今後の予測変電量等の情報を含んでいてもよい。今後の予測変電量とは、例えばメンテナンス等により変電量が増減することが分かっている場合には、発電量が増減する時間とその変電量の情報を含んでいてもよい。   (3) As information on the cost and expense of the power to be generated, for example, the unit price of power generated by each power plant is redistributed, and the unit price of power is calculated by adding the cost and cost required by the transformer. It may include information such as the amount of carbon dioxide generated per unit power of power, the number of times of power transformation (increases by 1 every time it passes through the transformer), and the predicted amount of transformation in the future. For example, when it is known that the amount of power change will increase or decrease due to maintenance or the like, the predicted amount of power change in the future may include information on the time when the power generation amount increases or decreases and the amount of power change.

末端の負荷や変電所から見れば、どこが上流側で最も近い発電所または変電所なのかを知ることが出来るが、末端の負荷や変電所で受信したこれらの情報の中身を解析することで、受電した電力がどのような経路を辿ってきたかを判断することができる。また、末端の負荷や変電所では、受電した電力の経路のみならず、受電した電力が発電に要したコストに関する情報も知ることが出来る。従って、末端の負荷や変電所は、受信した情報の出所を発電端である発電装置まで辿ることが可能な構造を有することになる。   If you look at the end load or substation, you can know which is the nearest power plant or substation upstream, but by analyzing the contents of the information received at the end load or substation, It is possible to determine what route the received power has taken. In addition, at the terminal load or substation, it is possible to know not only the route of the received power but also information about the cost of the received power required for power generation. Therefore, the load and the substation at the end have a structure that can trace the source of the received information to the power generation device that is the power generation end.

以上、本発明の一実施形態にかかる電力配電システム１００の構成について説明した。次に、本発明の一実施形態にかかる発電装置の構成について説明する。   The configuration of the power distribution system 100 according to the embodiment of the present invention has been described above. Next, the structure of the electric power generating apparatus concerning one Embodiment of this invention is demonstrated.

〔３〕本発明の一実施形態にかかる発電装置の構成
図２は、本発明の一実施形態にかかる発電装置１０１の構成について示す説明図である。以下、図２を用いて、本発明の一実施形態にかかる発電装置の構成について、発電装置１０１を例にして説明する。 [3] Configuration of Power Generation Device According to One Embodiment of the Present Invention FIG. 2 is an explanatory diagram showing the configuration of the power generation device 101 according to one embodiment of the present invention. Hereinafter, the configuration of the power generation device according to the embodiment of the present invention will be described using the power generation device 101 as an example with reference to FIG. 2.

図２に示したように、本発明の一実施形態にかかる発電装置１０１は、発電機２０１と、マイクロプロセッサ２０２と、モデム２０３と、電流測定部２０４と、ラインドライバ２０５、２０６と、キャパシタＣ１，Ｃ２と、抵抗Ｒ１と、を含んで構成される。   As shown in FIG. 2, the power generation apparatus 101 according to an embodiment of the present invention includes a generator 201, a microprocessor 202, a modem 203, a current measurement unit 204, line drivers 205 and 206, and a capacitor C1. , C2 and a resistor R1.

発電機２０１は電力を発電するものであり、本実施形態においては、発電機２０１では直流の電力を発電する。発電機２０１で発電された電力の電圧値の情報はマイクロプロセッサ２０２に送られる。発電機２０１で発電される電力の状況は、キャパシタＣ１への蓄電状況をモニタリングすることで逐一監視される。また、抵抗Ｒ１の両端の電位差から、発電機２０１で発電された電力の電流値を電流測定部２０４で測定する。電流測定部２０４で測定した電流値はマイクロプロセッサ２０２に送られる。   The generator 201 generates power. In the present embodiment, the generator 201 generates DC power. Information on the voltage value of the power generated by the generator 201 is sent to the microprocessor 202. The state of the electric power generated by the generator 201 is monitored step by step by monitoring the state of power stored in the capacitor C1. Further, the current measurement unit 204 measures the current value of the power generated by the generator 201 from the potential difference between both ends of the resistor R1. The current value measured by the current measuring unit 204 is sent to the microprocessor 202.

マイクロプロセッサ２０２には、発電機２０１が発電した電力の電圧値および電流値の情報の他、上述した（１）情報通信や電力配電システム１００のマネジメントに関する情報、（２）発電する電力の物理仕様に関する情報、（３）発電する電力のコストや経費に関する情報が送られてくる。具体的には、発電装置１０１を他の発電装置と識別するための発電所ＩＤ、発電装置１０１の位置情報その他の発電装置１０１に関する情報がマイクロプロセッサ２０２に送られる。マイクロプロセッサ２０２では、これらの情報を集約し、モデム２０３に送る。   In the microprocessor 202, in addition to the information on the voltage value and current value of the power generated by the generator 201, (1) information related to information communication and management of the power distribution system 100, and (2) physical specifications of the power to be generated. (3) Information on the cost and expense of power to be generated is sent. Specifically, a power plant ID for identifying the power generation device 101 from other power generation devices, position information of the power generation device 101 and other information related to the power generation device 101 are sent to the microprocessor 202. In the microprocessor 202, these pieces of information are collected and sent to the modem 203.

モデム２０３は、マイクロプロセッサ２０２から送られる情報を、発電機２０１で発電された電力に重畳できる形式に変調するものである。本実施形態においては、モデム２０３は、十分高い周波数帯域を使用して行われる情報信号の送受信における、信号の変調・復調を行うものである。モデム２０３で変調された情報は、ラインドライバ２０５、キャパシタＣ２を経由して、発電機２０１で発電された電力に重畳されて、発電装置１０１から情報Ｇ１として出力される。   The modem 203 modulates the information sent from the microprocessor 202 into a format that can be superimposed on the power generated by the generator 201. In the present embodiment, the modem 203 performs signal modulation / demodulation in transmission / reception of an information signal performed using a sufficiently high frequency band. The information modulated by the modem 203 is superimposed on the power generated by the generator 201 via the line driver 205 and the capacitor C2, and is output as information G1 from the power generator 101.

発電装置１０１からの情報Ｇ１を電力に重畳して出力する場合には、例えば、本件発明者と同一発明者による発明である特開２００８−１２３０５１号公報に記載された発明を用いることができる。発電装置１０１からの情報Ｇ１を電力に重畳して出力する場合には、当該発明のように、電力と情報とをパケット化し、電力パケットと情報パケットとを時分割で送信しても良い。このように電力生成元でパケットを生成して送信することで、電力消費元で電力を受電し、消費することが可能となる。もちろん、情報の電力への重畳手法については、かかる例に限定されないことは言うまでも無い。   In the case where the information G1 from the power generation device 101 is superimposed on the electric power and output, for example, the invention described in Japanese Patent Application Laid-Open No. 2008-123051 which is an invention by the same inventor as the present inventor can be used. When the information G1 from the power generation apparatus 101 is superimposed on the power and output, the power and the information may be packetized and the power packet and the information packet may be transmitted in a time division manner as in the present invention. Thus, by generating and transmitting a packet at the power generation source, the power consumption source can receive and consume the power. Needless to say, the method of superimposing information on power is not limited to this example.

以上、本発明の一実施形態にかかる発電装置１０１の構成について説明した。なお、上記では本発明の一実施形態にかかる発電装置の構成として発電装置１０１を例にして説明したが、発電装置１０２、１０３においても、発電装置１０１と同様の構成を有することが出来る。次に、本発明の一実施形態にかかる負荷１２１の構成について説明する。   The configuration of the power generation device 101 according to the embodiment of the present invention has been described above. In the above description, the power generation apparatus 101 is described as an example of the configuration of the power generation apparatus according to the embodiment of the present invention. However, the power generation apparatuses 102 and 103 can have the same configuration as the power generation apparatus 101. Next, the configuration of the load 121 according to the embodiment of the present invention will be described.

〔４〕本発明の一実施形態にかかる負荷の構成
図３は、本発明の一実施形態にかかる負荷１２１の構成について示す説明図である。以下、図３を用いて、本発明の一実施形態にかかる負荷の構成について、負荷１２１を例にして説明する。 [4] Configuration of Load According to One Embodiment of the Present Invention FIG. 3 is an explanatory diagram showing the configuration of the load 121 according to one embodiment of the present invention. Hereinafter, the configuration of the load according to the embodiment of the present invention will be described using the load 121 as an example with reference to FIG. 3.

負荷１２１は、本発明の電力受電装置の一例である。負荷１２１には、発電装置１０１において電圧Ｖ１で発電された電力および発電装置１０２において電圧Ｖ２で発電された電力が供給される。図３に示したように、本発明の一実施形態にかかる負荷１２１は、チャージコントローラ３０１と、モデム３０２と、ＤＣ／ＤＣコンバータ３０３と、マイクロプロセッサ３０４と、負荷３０５と、キャパシタＣ１、Ｃ２、Ｃ３、Ｃ４と、スイッチＳ１、Ｓ２と、を含んで構成される。   The load 121 is an example of the power receiving device of the present invention. The load 121 is supplied with the power generated at the voltage V1 in the power generation apparatus 101 and the power generated at the voltage V2 in the power generation apparatus 102. As shown in FIG. 3, the load 121 according to an embodiment of the present invention includes a charge controller 301, a modem 302, a DC / DC converter 303, a microprocessor 304, a load 305, capacitors C1, C2, C3 and C4 and switches S1 and S2 are included.

チャージコントローラ３０１は、供給された電力を用いて、発電装置１０１、１０２からの電力が供給されていない場合に負荷１２１の動作に用いられるキャパシタＣ３の充電を制御するものである。チャージコントローラ３０１によってキャパシタＣ３への過充電が防がれることになる。   The charge controller 301 uses the supplied power to control charging of the capacitor C3 used for the operation of the load 121 when the power from the power generation devices 101 and 102 is not supplied. The charge controller 301 prevents the capacitor C3 from being overcharged.

モデム３０２は、発電装置１０１、１０２から送信された情報Ｇ１、Ｇ２の変調・復調を行うものである。発電装置１０１、１０２から送信される情報Ｇ１、Ｇ２としては、例えば、１）情報通信や電力配電システム１００のマネジメントに関する情報、（２）発電する電力の物理仕様に関する情報、（３）発電する電力のコストや経費に関する情報がある。本実施形態においては、モデム３０２は、モデム２０３と同様に、十分高い周波数帯域を使用して行われる情報信号の送受信における、信号の変調・復調を行うものである。モデム３０２で復調された情報はマイクロプロセッサ３０４に送られる。   The modem 302 modulates and demodulates information G1 and G2 transmitted from the power generation devices 101 and 102. Examples of information G1 and G2 transmitted from the power generation devices 101 and 102 include 1) information related to information communication and management of the power distribution system 100, (2) information related to physical specifications of power to be generated, and (3) power to be generated. There is information about costs and expenses. In the present embodiment, the modem 302 performs signal modulation / demodulation in transmission / reception of an information signal performed using a sufficiently high frequency band, like the modem 203. Information demodulated by the modem 302 is sent to the microprocessor 304.

ＤＣ／ＤＣコンバータ３０３は、発電装置１０１、１０２から電力網を通じて供給された電力を、負荷３０５が必要とする電流・電圧に変換するものである。   The DC / DC converter 303 converts the power supplied from the power generators 101 and 102 through the power network into the current / voltage required by the load 305.

マイクロプロセッサ３０４は、モデム３０２で復調された情報Ｇ１、Ｇ２を受け取り、受け取った情報Ｇ１、Ｇ２に基づいてスイッチＳ１、Ｓ２のスイッチング動作を制御するものである。また、マイクロプロセッサ３０４は、負荷３０５における電力消費状況をモニタし、負荷３０５における電力消費状況に応じてスイッチＳ１、Ｓ２のスイッチング動作を制御する。負荷３０５は、発電装置１０１、１０２から供給される電力を実際に消費するものである。なお、スイッチＳ１、Ｓ２は、各種スイッチング素子、例えばＭＯＳＦＥＴ（Ｍｅｔａｌ−Ｏｘｉｄｅ−Ｓｅｍｉｃｏｎｄｕｃｔｏｒ Ｆｉｅｌｄ−Ｅｆｆｅｃｔ Ｔｒａｎｓｉｓｔｏｒ）を用いてもよい。   The microprocessor 304 receives the information G1 and G2 demodulated by the modem 302, and controls the switching operation of the switches S1 and S2 based on the received information G1 and G2. In addition, the microprocessor 304 monitors the power consumption status in the load 305 and controls the switching operations of the switches S1 and S2 according to the power consumption status in the load 305. The load 305 actually consumes the power supplied from the power generation devices 101 and 102. The switches S1 and S2 may use various switching elements, for example, MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor).

例えば、負荷１２１に、発電装置１０１、１０２の両方からの電力が供給されている場合において、モデム３０２で復調された情報Ｇ１、Ｇ２をマイクロプロセッサ３０４で受け取ったときを考える。このとき、発電装置１０１の方が発電装置１０２よりも絶対的な距離が近いことが分かれば、発電装置１０１から供給される電力を優先して消費するために、スイッチＳ１を閉じ、スイッチＳ２を開くよう、マイクロプロセッサ３０４で制御してもよい。   For example, consider the case where the microprocessor 304 receives the information G1 and G2 demodulated by the modem 302 when the load 121 is supplied with power from both the power generation devices 101 and 102. At this time, if it is known that the absolute distance of the power generation device 101 is shorter than that of the power generation device 102, the switch S1 is closed and the switch S2 is turned off in order to preferentially consume the power supplied from the power generation device 101. The microprocessor 304 may control the opening.

また例えば、モデム３０２で復調された情報Ｇ１、Ｇ２をマイクロプロセッサ３０４で受け取った結果、発電装置１０１から供給される電力の方が発電装置１０２から供給される電力よりも単位電力に対する二酸化炭素の発生量が少ないことが分かれば、発電装置１０１から供給される電力を優先して消費するために、スイッチＳ１を閉じ、スイッチＳ２を開くよう、マイクロプロセッサ３０４で制御してもよい。   Further, for example, as a result of receiving the information G1 and G2 demodulated by the modem 302 by the microprocessor 304, the power supplied from the power generation apparatus 101 generates more carbon dioxide per unit power than the power supplied from the power generation apparatus 102. If it is known that the amount is small, the microprocessor 304 may control the switch S1 to close and the switch S2 to open in order to preferentially consume the power supplied from the power generation apparatus 101.

また例えば、モデム３０２で復調された情報Ｇ１、Ｇ２をマイクロプロセッサ３０４で受け取った結果、発電装置１０１から供給される電力の方が発電装置１０２から供給される電力よりも単位電力あたりの単価が少ないことが分かれば、発電装置１０１から供給される電力を優先して消費するために、スイッチＳ１を閉じ、スイッチＳ２を開くよう、マイクロプロセッサ３０４で制御してもよい。   Further, for example, as a result of receiving the information G1 and G2 demodulated by the modem 302 by the microprocessor 304, the power supplied from the power generation apparatus 101 has a lower unit price per unit power than the power supplied from the power generation apparatus 102. If it is understood, the microprocessor 304 may be controlled to close the switch S1 and open the switch S2 in order to preferentially consume the power supplied from the power generation apparatus 101.

また例えば、モデム３０２で復調された情報Ｇ１、Ｇ２をマイクロプロセッサ３０４で受け取った結果、発電装置１０１から供給される電力の方が発電装置１０２から供給される電力よりも変電回数が少なければ、発電装置１０１から供給される電力を優先して消費するために、スイッチＳ１を閉じ、スイッチＳ２を開くよう、マイクロプロセッサ３０４で制御してもよい。   Further, for example, if the microprocessor 304 receives the information G1 and G2 demodulated by the modem 302, if the power supplied from the power generation apparatus 101 has a smaller number of transformations than the power supplied from the power generation apparatus 102, power generation In order to preferentially consume the power supplied from the device 101, the microprocessor 304 may control to close the switch S1 and open the switch S2.

また例えば、モデム３０２で復調された情報Ｇ１、Ｇ２をマイクロプロセッサ３０４で受け取った結果、装置のメンテナンス等によりある時点より所定の期間は発電装置１０１の発電量が低下することが分かれば、当該時点までは発電装置１０１から供給される電力を優先して消費し、当該時点が到達すると、上記期間の間は発電装置１０１から供給される電力を優先して消費するように、スイッチＳ１、Ｓ２のスイッチングを制御してもよい。   In addition, for example, if the microprocessor 304 receives the information G1 and G2 demodulated by the modem 302, if it is known that the power generation amount of the power generation apparatus 101 decreases for a predetermined period from a certain time due to maintenance of the apparatus, The switches S1 and S2 are used so that the power supplied from the power generator 101 is preferentially consumed, and when the time reaches, the power supplied from the power generator 101 is preferentially consumed during the period. Switching may be controlled.

マイクロプロセッサ３０４によるスイッチＳ１、Ｓ２のスイッチング制御のルールを、予めマイクロプロセッサ３０４に設定しておくことで、当該ルールに応じてスイッチＳ１、Ｓ２の切り替えを制御することができる。また負荷１２１の使用状況に応じて、マイクロプロセッサ３０４によるスイッチＳ１、Ｓ２のスイッチング制御のルールを任意に設定することで、当該ルールに応じてスイッチＳ１、Ｓ２の切り替えを制御することができる。もちろん、マイクロプロセッサ３０４によるスイッチＳ１、Ｓ２のスイッチングの制御の条件は、上述した例に限られないことは言うまでも無い。   By setting a rule for switching control of the switches S1 and S2 by the microprocessor 304 in the microprocessor 304 in advance, switching of the switches S1 and S2 can be controlled according to the rule. Further, by arbitrarily setting a switching control rule for the switches S1 and S2 by the microprocessor 304 according to the usage state of the load 121, switching of the switches S1 and S2 can be controlled according to the rule. Of course, it goes without saying that the conditions for controlling the switching of the switches S1 and S2 by the microprocessor 304 are not limited to the above-described example.

なお、図３に示した構成では、スイッチＳ１、Ｓ２にそれぞれ並列にキャパシタＣ１、Ｃ２が設けられている。キャパシタＣ１、Ｃ２は直流の電流を遮断し、十分高い周波数帯域を使用して行われる情報信号は通過させる。従って、スイッチＳ１、Ｓ２が開いている場合であっても、発電装置１０１、１０２から電力網を通じて送信される情報を受信することが可能となる。   In the configuration shown in FIG. 3, capacitors C1 and C2 are provided in parallel with the switches S1 and S2, respectively. Capacitors C1 and C2 block a direct current, and pass information signals performed using a sufficiently high frequency band. Therefore, even when the switches S1 and S2 are open, it is possible to receive information transmitted from the power generation apparatuses 101 and 102 through the power network.

図３に示した構成では、電源としてキャパシタＣ３を負荷１２１の内部に設けているが、本発明はかかる例に限定されないことは言うまでも無い。例えば、キャパシタＣ３の替わりに、またキャパシタＣ３と共に、負荷１２１の内部に二次電池を設けるようにしてもよい。   In the configuration shown in FIG. 3, the capacitor C3 is provided inside the load 121 as a power source, but it goes without saying that the present invention is not limited to such an example. For example, a secondary battery may be provided inside the load 121 in place of the capacitor C3 and together with the capacitor C3.

以上、本発明の一実施形態にかかる負荷１２１の構成について説明した。なお、本実施形態においては、本発明の電力受電装置の一例として負荷１２１を例示して説明したが、本発明の一実施形態にかかる変電装置１１１、１１２についても本発明の電力受電装置の一例である。変電装置１１１、１１２は、発電装置１０１、１０２、１０３で発電された電力の供給を受けて、予め定めた電圧・電流に変電して出力するものである。ここで、発電装置１０１、１０２、１０３から供給された電力の発電効率を考慮に入れて、変電装置１１１、１１２において、どの発電装置から供給された電力を優先して変電し、後段の電力網に出力するかを判断しても良い。この場合には、後段の電力網に情報を送信するために、変電装置１１１、１１２の内部に情報の変調および復調を実行するモデムを設けていても良い。   The configuration of the load 121 according to the embodiment of the present invention has been described above. In the present embodiment, the load 121 is illustrated as an example of the power receiving device of the present invention. However, the transformers 111 and 112 according to the embodiment of the present invention are also examples of the power receiving device of the present invention. It is. The transformers 111 and 112 are supplied with power generated by the power generators 101, 102, and 103, transformed into a predetermined voltage / current, and output. Here, taking into account the power generation efficiency of the power supplied from the power generation devices 101, 102, and 103, the power transformation devices 111 and 112 prioritize the power supplied from which power generation device and transform it into the subsequent power network. You may judge whether to output. In this case, a modem for performing modulation and demodulation of information may be provided inside the transformers 111 and 112 in order to transmit information to the power network at the subsequent stage.
